Fleet electrical and tachograph parts
Tachograph senders and speed sensors for trucks and buses
KITAS II+ tachograph senders, M22 speed pulse generators, probe-type senders and 24 V gauges for commercial fleets. Read the part number off the old sender, check the probe length and connector, and order the matching part on Omnipart.

Speed and tachograph senders by type
Identify the sender from the old part: where it fits on the gearbox, the probe length or thread, the connector and what reads the signal. A tachograph head expects an encrypted KITAS signal; a speedometer or fleet unit reads an inductive one.
| Sender type | Example part number | Fits | Signal |
|---|---|---|---|
| KITAS II+ tachograph sender | 2171-20002115 | Probe bore, 19.8 mm probe, 4-pin round terminal (other lengths up to 115 mm) | Encrypted, for digital tachographs |
| KITAS screw-on sender | 2171-01000010 | M22 x 1.5 cable port, female, round pin | Encrypted, for digital tachographs |
| Speed pulse generator, 4-pin | 2159-01000000 | M22 x 1.5 cable port, female connector (2159-02000000 is the male) | Inductive, for speedometers and fleet units |
| Speed pulse generator, 3-pin | 2155-01000000 | M22 x 1.5 cable port, 3-pin female | Inductive |
| Integrated probe sender | 2159-20102201 | Probe bore, 35 mm probe, 4-pin round terminal (also 19.8, 25, 63.2 and 90 mm) | Inductive |
Fleet parts by category
Sensors & Senders
334Speed sensors and senders selected for truck and bus fitment. Here the question is which pulse generator matches your gearbox drive and what reads the signal at the other end, a speedometer, a fleet unit, or a certified tachograph. Filter by probe length, thread, connector and output (inductive for instruments, encrypted for KITAS heads) so the part seats first time across a mixed fleet.

Read guideOrdering for a fleet
- One vehicle
- Order the sender by part number on Omnipart. The price shown is the price of the part; delivery is added at checkout.
- A mixed fleet
- List the part numbers and quantities on one quote request and we price the order as a whole.
- Unreadable label
- Send the probe length, thread, connector and a photo, with the vehicle and gearbox, and we match the part.
- Tachograph work
- Fit the KITAS sender the head expects, then have the chain recalibrated and sealed by an approved workshop.
